APPARATUS FOR GENERATlNG GAS 0R VAPOR FROM LlQUlD HYDROCARBONS.

EEPEOIFLCATION forming part of Letters Patent No. 300,752, dated June 24,1884.

Application filed June 9, 1882. (No model.)

Be it known that I, AUGUSTIN I. AMBLER, a citizen of the United States, residing in \Vashington, in the District of Columbia, have invented a certain new and useful Improvement in Apparatuses for Generating Gas or Vapor from Liquid Hydrocarbons; and I do hereby declare the following to be a full, clear, and exact description of my invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing's, and to the letters of reference marked thereon, and which form a part of this specification.

My invention consists in the novel construction and combination of parts of the apparatus, as hereinafter pointed out and claimed.

In the accompanying drawings, Figure 1 is a vertical section of the entire apparatus. Fig. 2 is a longitudinal sectional view of an inspirator such as may be used, the same being old and not of my invention.

Letters of reference refer to various parts of the machine.

A designates the outer cylinder; A, steamspace between the outer, and inner cylinders.

'13 is the inner cylinder with its corrugations to give additional heating-surface; B, the chamber of the inner cylinder.

0 designates the dome-chamber; G, the pipe connected therewith for the passage of the gas to the dome-chamber, where it is held under pressure by means of the pipes and valves connected therewith; D and D, the pipe and valve for conducting the gas from the generator to the furnace for use without the intervention of the trap.

E is the furnace, and E is the chamber around the apparatus, in which is located the superheater.

F is a coil of pipe around the generator; F, pipe connecting superheater with steamchamber; Fflpipe connecting superheater with steam-boiler. (Notshowu) G is a pipe connecting with upper part of inner or generating chamber; G, pipe connecting with bottom of generating-chamber; G", pipe and glass gage connecting pipesG and G, to show the 011 or vapor in the generating-chamben H is the pipe connecting steanrehamber A with gas-chamber B. H is the valve to open the flow of steam thereto.

I I is the inspirator. I is the feed-pipe con necting inspirator with the perforated feedpipe 1 I is the perforated oil or supply pipe, connected with the feed of the inspirator.

I is the pipe connecting inspirator withthe oil-supply, drawn from a tank under ground. I is the overflow-pipe of the inspirator.

. J is the vapor-pipe to convey gas to the inspirator to operate the same.

a b 0 are the valves to operate the inspirator. Any ordinary hand-pump may be used to supply the first oil to the apparatus, and until the pressure of the vapor, as indicated by the gage, is sufficient to cause the inspirator to work; or steam may be employed to operate the inspirator until the pressure of gas is sufficient. The working parts of the inspirator are not shown, as I do not confine myself to any particular form of combination to produce the result, the application being in the nature of a vacuum and a siphon.

K is the pyrometer to show the heat.

K is the pressure-gage.

To the apparatus should be attached a suitable safety-valve.

L isthe cylinder of the trap.

M isthe pipe to convey the gas from the vapor-chamber to the trap L. l

M is the pipe from the trap to convey the gas to the burners.

M is the pipe leading from the trap of the feed-pipe of the inspirator to carry back into the generating-chamber any oil that may follow'the gas to the trap. As the gas passes out of the pipe M it will fill the cylinder of the trap, and the oil will be drawn into the feed of the inspirator by the connecting-pipeM",a11d returned to the generating-chamber with the vapor by which the inspirator is operated.

M is the draw-off pipe to the trap.

The construction of the apparatus is so clearly shown in the drawings as to need no special description further than to say that the cylinders are to be made of the best quality of cast steel or iron in the form illustrated by the drawings. The cylinders are made from pat terns turned and coved out in the form do V to make the corrugations shown for forming ing-valves a b c of the inspirator, the oil is drawn up by means of the vacuum created by the gas passing through the inspirator to the apparatus from the tank below through the pipe I, and inspirated through the feed-pipe I and perforated pipe I into the generatingchamber B. The operation is continuous as long as there is a working oil-supply.

The overflow-pipe is shown at I.

I disclaim any special combination of mechanical elements heretofore known or used in an inspirator, and claim only such application to a vapor-fuel apparatus as enables me to use vapor instead of steam to operate the inspirator.

Having thus describ (1 my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I11 combination, the inelosingicylinder A, the corrugated cylinder A, inclosed within the same so as to leave asteam-spaee between, and the pipe 0, communicating with the corrugated. cylinder by which it is inclosed near the bottom, substantially as shown.

2. The corrugated generating-chamber B, surrounded by the corrugated steam-chamber A, the inspirator-chambers II, the feed-pipe I, the perforated oil-pipe I", the oil-supply pipe 1 the overflow-pipe I, the vapor-pipes J and M, the cylinder-trap L, the condensation return-pipe M the gas-pipe M, and the steam-pipe H and H, all combined and relatively arranged substantially as shown and described.

3. The combination of the cylinder A, the cylinder B, the dome G, the pipe 0, and the I pipe and valve D and D.

4. The superheater F, pipes F and F, the steam-chamber A, the pipe and valve H and H, the dome and pipe 0 and O, and the pipe and valve D and D, combined and relatively scribed, the inner one being so constructed as both the steam and generating chambers. The two cylinders are bolted together at the top by means of flanges cast thereon or they may be made in cast angle-iron and riveted thereto. A dome-top forming the chamber 0 is applied, with which is connected the long gaspipe 0 for the passage of the gas or vapor,- and a long steam-pipe, H, passes down through the dome and gas-pipe to convey superheated steam to the bottom of the generating-chamber of the apparatus, to which suitable gages and valves are to be attached. A coil superheater surrounds the outer cylinder, and is connected therewith and with a steam-boiler, (not shown,) so that the steam may flow from the boiler through the superheater to all parts ofthe apparatus. The apparatusis then placed in a suitable brick-work chamber over a furnaee, and when the connections are all made is ready for operation.

The mode of operation is as follows: Fire being made in the furnace with any suitable material and a proper degree of heat (say a low black heat) being attained, steam is let on by means of the pipe connecting the steamboiler (not shown) with the superheater and the chamber A. Oil is then injected or inspiratedinto the generating-chamber through the perforated pipe until a supply is obtained, which need not exceed from five to six gallons in a full-size working-machine, the quantity being shown by the glass-tube gage connected with the inner chamber by the pipes G and G, when the valve in the pipe H is opened, permitting the steam to pass down through said pipe to the bottom of theinner chamber, where it will mix and combine with the oil and vapors of the hydrocarbons employed, the combined vapors thus generated being retained under heat and pressure until from ten to twenty pounds to the square inch are shown by the gage, when the valves in the pipes leading to the burners in the furnace (either through the trap or by direct connection with the burners) are opened for use. The gas will then flow in regulated quantities to the burners where it will be ignited and burn as required. Caution should be observed in opening the way to the burnl jacket, ers thatno gas may accumulate in the furing-chamber, the pipes G and G with pipe nace, to avoid which the. operating valve and glass tube G the superheaterF and conshould be opened very slightly and the gas necting-pipes F and F pipe and valveH and ignited as soon as it reaches the burners in a H, pipe 0, dome O, and pipe and valveD and small bead, which may then be increased to D, and oil-supply pipe I, substantially as meet the demand required. The gas then shown, and for the purpose set forth. flows from the gas-chamber 0 through the AUGUSTIN I. AMBLER. pipe J to the inspirator to operate the same to supply oil to the apparatus. By this means arranged substantially as stated. V 5. The combination of the oil-feed pipe, the inspirator, and the generator with gaspipes M and M, the cylinder L, and pipes M for-returning any liquid of condensation to the generator by means of the feed-pipe of the inspirator, substantially as stated. 6.
